There are 8 coins total, so that is your denominator.
There are 3 dimes and 2 quarters, so add them together and you get 5 which is your numerator.
5/8 should be the fraction you end up with :)
Answer:
40°
Step-by-step explanation:
The measure of the right angle is 90°.
The measures of the angles 10° and 2x add up to the measure of the right angle.
2x + 10° = 90°
2x = 80°
x = 40°
Assuming the question is "at what rate did the chemist heat the solution," the answer is the chemist heated the solution at +4.5 degrees Celsius per minute.
75-21=54
54/12=4.5
Answer:
102 and 109
Step-by-step explanation:
create an equation to solve:
(x-7) + x = 225
2x -7 = 225
<u> +7 +7</u><u> </u><u> </u> add 7 to both sides
<u>2x</u> = <u>218</u>
2 2 divide both sides by 2
x = 109
<u>109 is the first number</u>
then you solve for the other number
x-7= ?
109 - 7 = 102
<u>102 is the 2nd number</u>
